The Gasuden Jimpu or Kamikaze (later produced by Hitachi) was a Japanese seven-cylinder air-cooled radial aircraft engine from the 1920s, 1930s and 1940s. It was the first aircraft engine produced by Tokyo Gas and Electric (神風, 東京瓦斯電気工業, Tokyo Gasu Denki), often abbreviated to Gasuden, and the first production engine produced in Japan. It was produced in large numbers to power training and light aircraft before and during the Pacific War.
